Rubber sole A snug fit that disappears on your foot. The Nike React Phantom Run Flyknit 2 offers versatility for the everyday runner. Building on the foundations of its predecessor, the shoe expands on its laceless design by adding secure support that seems to 'disappear' on the foot. More foam means better cushioning, keeping you comfortable as you run. Secure Feel The latest Flywire technology features an elastic design that intertwines with the Flyknit upper, helping the foot feel secure while running. Lightweight and breathable FlyKnit Loft uses 3 layers of the forefoot. They combine for a lightweight, breathable, and durable feel that keeps your foot comfortable. Nike React's smooth and responsive technology provides a soft, responsive ride. It provides support for the 3 phases of a runner's pace: flexibility at the tip of the foot, a smooth ride in mid-position, and cushioning on contact. The increased rubber on the sole helps provide better traction and durability. Stamping around the heel makes you feel confident so you can focus on your journey.
